To @ZZ whom it may concern:

Be it known that we, MARcUs T. MURPHY and JUNIUs A. MURPHY, bothof New Orleans,

n I -new and improved machine for weaving oil-z press mats in such a manner as to produce a strong, compact, and uninjured mat.

The invention consists of auxiliary pusherbars, used in connection with the regular mat- I plates.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of thisl specification,

in which sirnilarlletters of reference indicate j plates `F, when in position, rest against the outcorresponding parts in all the'gures.

Figurel is a plan view of a mat-Weaving i frame providedwith'our improvement, parts being broken out. Fig. 2 is a side elevation oi'cne of the mat-plates. Fig. 3 isa vertical crosssection of the same on the linew w of Fig. 2. Fig. 4 is a 'side elevation of one'l of the pusher-bars. Fig. 5 is a vertical cross-section ofthe same on the line y yjof Fig. 4. Fig. 6 is a longitudinal side elevation of the machine on the line zzof Fig. l. Fig. 7 is avertie-al crosssection of the saine on the line u u of Fig.4 1. Fig. 8 is a plan View, on an enlarged scale, showing the warp in position on they rods and the woof beingintroduced`as' the said rods are withdrawn, parts being broken away and shown in section.

Heretoforein making oil-press mats the mat-I plates could not be pressed toward each other with a great pressure after the Warp had been made without breaking the plates and injuring the edges-of the warp..l In our frame, presently-to be described,.we avoid these difficulties, and provide a machine whichy can stand a great hydraulic or other pressure for pressing the warps into a compact form without bieaking the 1nat-plates or injuring the warps.

5 0 The mat-platesA A on one side andthe mat-plates B B of the opposite side are probe seen that the mat-plates are .veryrnateriall y vided' with slotsC of like shape, but arranged insuch a manner that the slots C ottwo opposite plates, A andB'or A and'fgB, vrare. not directly opposite each. 'other,.but are arranged alternately, so that when the woef-rods D are held in place onthesaid mat-plate, yas shown in Figs. 1, 6, vand 7, thenv the bearing of, say, the second'rod D inthe plate'A is in the left end ofthe slot C, while the bearing of 6o i said rod D in the opposite plate, B, is in theVK right end of the slot C of the plateB. `The ne'xtcr third rod Dhas itsbearing in the right en'd of the slot C ofthe plate vA,while the other bearing of the same'rcd is in the left end of the 6 5 second slot C in the plate Bfand so on.

Into the slots Clit the projections. or lugs E,

secured by rivets or other means to the pusher. 4 y u bars F, of which one is used for each mat-plate. Thelugs E; when introduced in vthe slots C,`v leave vspace for the passage of the Woof-rodsA D, e as shown in Fig. 6said rods D being held in e place in theslots C by the lugs E. The pusherside of the respective mat-plates, and the inner ends ofthe lugs E rare Hush with ythe inside of the mat-plates. i l The operation is as follows: The mat-plates A A and'B B andthe respective pusher-bars. F are fitted to each other, and the Woof-rods D are then putin place, passingthroughthe openings left in Ithe slots() by the lugs E, as before described. Hydraulicor other pressure is now ,appliedto' force-'the mat-platesiA B l and A B toward each otheruntil they assume arepressed together until the desired-varying width of the intended mat is reached. 'It will strengthenedby the pusherbars,`.so that av great pressure can beapplied for pressing the n f respective mat-plates toward each 0ther,thus forming a compactwvarp, theedgesfof which` will not be injured by reason of*` thelugs E exi tending through'the mat-plate'slots C vflush 95.-, y

with theinner sides, thereof.` Ifthese slotsY were left fully open, the outer warp-ropeswoulfd be pressed intov the slots and broken, 'thereby injuring the edges of the warp.VV vThe lockingbars G, of the usual construction, arel then placed upon the plates A Band A B, as shown in Fig. 1, so` as to hold the respective 'Inat-- "the form shown in Fig. l, so that thewarps g plates in a locked position after the hydraulic lpressure is removed. The pusher-bars'F are then removed by being pulled outward. The Warps are now ready to receive thewoofrope, which is inserted as follows: The first woofrod D on one end of the machine is removed, and the Woof-rope is passed through the aperture formed by said rod by first passing the end of the Woof-rope into the first aperturein the plate A in the direction of the arrow a', (shown in Fig. 8,) and through the warp-aperture and through the first slot C in thematplate B. The second Woof-rod D is then -removed and the end of the woofrope is returned to the other side through the aperture formed by said second Woof-rod D.

It will be seen that on the turning of the Woof-rope the bend of the rope -will be in the slot C in the plate B, so that the Woof-rope lies iiush against the edge of the Warp between the first two apertures. rIhe Woof-rope, on passing through the second slot C in the plate A, is at the left end of said slot, and when the third rod D is now removed and the Woof-*rope is again returned to the other side through the aperture formed by the third rod, then the bend of the Woof-rope is frmed in the second slot C of the plate A and rests directly against the edge of the warp. This operation is continued until all the Woof-rods D are removed and the Woof-rope is passed through the apertures inthe warp formed by said rods. The

Woof-*rope is then fastened "in the usual man i ner, after which the locking-bars G are removed from the mat-plates A B and A B', and then the latter are removed from the finished mat.

In Fig. 8 the warp-ropes are shown somewhat apart in order to illustrate clearly the Woof-rope.

Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is

' 1. In a frame for use in the manufacture of oil-press mats, the combination, with the matplates, of pusher-bars held on said mat-plates,

substantially as shown and described.

2. In a frame for use in the manufacture of oil-press mats, the combination, with the matplates and Woof-rods, of pusher bars held against the outside of said mat-plates, substantially as sho'wn and described.

3. In a frame for use in the manufacture of oil-press mats, th'e combination, with the matplates having slots, of pusher-bars provided with lugs tting into said slots, so as to leave space for the Woof-rods, substantially as shown and described.

4. `In a frame for use in the manufacture of oil-press mats, the combination, with the matplates, each having slots, of pusher-bars resting against theoutside of said mat-plates and provided with lugs projecting inward from said pusher-bars into said slots inthe mat-V plates, and Woof-rods held in openings between the mat'plates and said lugs, substantially as Y shown and described.
